procmail error prevents authenticated smtp

Virtualmin
1

Dear MB,

I’ve got an virtualmin machine based on SLES11.

The problem occours when postfix hands over the mail to procmail (as
specified in .forward), from the procmail log I see the following error:

check: no loaded plugin implements ‘check_main’: cannot scan! at
/usr/lib/perl5/vendor_perl/5.10.0/Mail/SpamAssassin/PerMsgStatus.pm line
164.

I’ve checked the rules and v320.pre contains the line:
loadplugin Mail::SpamAssassin::Plugin::Check

Said perl module is installed.

Does anybody know what is wrong and how I am able to fix it?

Howdy,

Yeah, SLES11 isn’t one of the Virtualmin supported distros, so it’s possible you could run into some strange problems.

I hadn’t heard of that problem before, but doing some digging on Google, and this fellow here seemed to run into a similar problem:

http://www.mail-archive.com/users@spamassassin.apache.org/msg43027.html

Does anything in there help?

One of the things they suggested doing was to run “spamassassin -D --lint”, and verify that the config file that loads that particular plugin is being loaded as expected.

Hi Forum,

Mnt_shred asked me to answer this for him do the the technical nature in this reply.

-Eric, I’ll try to reply to the fullest of my ability.

  1. The module that is causing trouble is according to CPAN fine:
    cpan> install Mail::SpamAssassin::Plugin::Check
    lots of text later
    Mail::SpamAssassin::Plugin::Check is up to date (undef).

  2. The module is nicely loaded from when I execute “cat some.mail.file|spamassassin -D --lint” from CLI:
    [12825] dbg: plugin: loading Mail::SpamAssassin::Plugin::Check from @INC

  3. There are some errors, warnings and failures which can be ignored (iyam) because these aren’t related to the problem or are for unused parts of SA:
    c:~ # grep -i error out.D.lint.txt
    c:~ # grep -i warn out.D.lint.txt
    [12825] dbg: config: warning: score set for non-existent rule OUTLOOK_3416
    [12825] dbg: config: warning: score set for non-existent rule RCVD_IN_DOB
    [12825] dbg: config: warning: score set for non-existent rule DNS_FROM_DOB
    [12825] dbg: config: warning: score set for non-existent rule XMAILER_MIMEOLE_OL_C9068

Failed, but these aren’t necessary.
c:~ # grep -i fail out.D.lint.txt
[12825] dbg: diag: module not installed: Mail::SPF::Query (‘require’ failed)
[12825] dbg: diag: module not installed: IP::Country::Fast (‘require’ failed)
[12825] dbg: diag: module not installed: Razor2::Client::Agent (‘require’ failed)
[12825] dbg: diag: module not installed: Net::Ident (‘require’ failed)
[12825] dbg: diag: module not installed: IO::Socket::INET6 (‘require’ failed)

[12825] dbg: diag: module not installed: Mail::DKIM (‘require’ failed)
[12825] dbg: diag: module not installed: Encode::Detect (‘require’ failed)

Given point 2, I have the strong suspicion that the problems stem from a misconfiguration of the PERL environment once executed from prostfix/procmail since running from CLI doesn’t render the same problems. I’m near n00b when it comes to PERL, so I have no clue where to look for answers on this one. :frowning:

I’ve attached the output of -D --lint. I hope it helps.

Thanks in advance!
